Nodejs: How can i simply get the request body using express4?

Question

Now that express is not shipped anymore with middleware that fills the req.body variable i am fighting to get req.body filled again. I am sending a POST request to /xyz/:object/feedback.

here my code:

app.post('/xyz/:object/feedback', function(req, res)
{
    console.log('Feedback received.');

    console.log('Body: ', req.body); // is not available :(

    res.set('Content-Type', 'text/plain; charset=utf8');
    res.send(result ? JSON.stringify(req.body) : err);
});

I tried to use body-parser already, but "Feedback received." never got logged to my console. So something seems to get stuck here:

var bodyParser = require('body-parser');
app.use(bodyParser);

How can i get req.body filled? (i need some working code)

The problem can be in your path `/xyz/:object/feedback`. Do you send a post request to correct url? Also try this `app.use(bodyParser())` instead of passing whole module. — 0101, May 30 '14 at 12:01
yes, i send a post request to the correct url (i can see the debug output) when i don't use bodyParse — Thariama, May 30 '14 at 12:06
And what about `app.use(bodyParser())`? This is possibly the problem. — 0101, May 30 '14 at 12:07

The problem is that you pass the whole module to the use method not the required instance.

Instead of this:

app.use(bodyParser);

do

app.use(bodyParser());

You need to do app.use(bodyParser()).

bodyParser() will return a function with what to use. bodyParser on its own is an invalid function for Express.

@NikolayLukyanchuk i recognized the problem on my own, it's not my fault 0101 only posted a comment. – Scimonster May 30 '14 at 12:11
@Thariama I gave an example. Add the parentheses to call the function. – Scimonster May 30 '14 at 12:12
